Re: [TRNSYS-users] TRNSYS-users Digest, Vol 119, Issue 23

Enyuan,
  The "more" button next to that input is a good place to start for questions like this. In this case, the value determines the fraction of the total air flow through the heat pump that will be outdoor air and the fraction that will be return air. If you set the value to 1 then no return air will be used and the heat pump will supply only conditioned outdoor air to the space.
regards,
 David

Dear David,

I do still have one more question, though. What's the guideline for setting up the "outdoor air damper position" parameter? I tried 0, 0.5 and 1. They produced very different results. Is there some empirical number for this parameter? Thanks!

best regards,
Enyuan
